New Invention for Barbers??

Found this patented new apparatus online…..







Well… Not sure what to think of this one. Four guys have come up with the idea of designing a detachable comb/shears apparatus, so instead of using 2 hands to do your scissor over comb technique, you can go ahead and just use the one hand!!!!
Sure hope they get this one made, I would love to try it for those full on barbering days and especially when I’m feeling lazy!!
